Abstract Nanostructured materials have demonstrated superior radiation-damage tolerance compared to their coarse-grained counterparts, contributing the extended lifespan of nuclear materials. However, mechanisms underlying this enhanced irradiation resistance remain unclear. In study, we present atomistic simulations investigate impact Cu/W heterophase interface on evolution irradiation-induced defects. The simulation results reveal that interfaces can act as defect sinks, effectively...
Molecular dynamics simulations were performed to study the diffusion behavior of hydrogen isotopes in single-crystal tungsten temperature range 300–2000 K. The show that coefficient H exhibits non-Arrhenius behavior, though this deviation from Arrhenius is slight. Many-body and anharmonic effects potential surface may induce slight isotope-dependence by activation energy; however, dependence pre-factor on isotope mass diminished. simulation results for H-atom migration near W surfaces...
Molecular dynamics (MD) is an important tool for investigating primary radiation damage in materials. Electronic effects, including electronic stopping power (se) and electron–phonon coupling (EPC), have a significant influence on high-energy many metals. Based MD, this study investigated the role played by effects collision cascade α-zirconium (α-Zr). The results show that when dominant type of cascades unconnected subcascades, EPC obviously affects evolution cascades. incorporation can...
